CVG - Forza Motorsport 4 review: Supercharged sequel?

CVG - "Without wanting to effectively bolt a turbo onto the already highly fuelled Forza vs Gran Turismo debate, it's become impossible to review the latest iteration of one series without acknowledging the other"

"the behaviour of Forza 4's cars represents what non-GT5 owners will rightly proclaim to be the pinnacle of the console driving experience."

Does that mean that the car behaviors are better in GT5 or that GT5 owners just wouldn't ever admit it?

I remember IGN saying GT5 was a 10/10 racing simulation in a 5/10 game...which as an owner of GT5 is probably true, judging from the the F4 demo, driving in GT5 feels more realistic but GT5 has so many flaws.
